실험 절차

A mixture of 2-[(2-methoxy-pyridin-4-ylmethyl)-amino]-benzoic acid (Step A, 516 mg, 2.0 mmol), 7-amino-4,4-dimethyl-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester (552 mg, 2.0 mmol), TBTU (0.706 g, 2.2 mmol), and DIEA (0.7 mL) in 30 mL of CH2Cl2 was stirred at RT for 2 h. The mixture was diluted with more CH2Cl2. The organic layer was washed with water, brine, and dried with MgSO4. The solution was filtered, condensed, and the residue was purified by flash column chromatography (0 to 30% of EtOAc in CH2Cl2) to obtain the titled compound as oil. MS (ES+): 517.2 (M+H)+. Calc'd for C30H36N4O4-516.27.
